The Sierra Club 20s & 30s section has been around for over 35 years. We're technically called the 20s & 30s Singles Section but we are open to couples, divorcees, and anybody else looking for a good time. We're an outdoors group catering to those in their 20s & 30s. We have hikes, camping trips, snow trips, and social events all over LA and the valley. We also have multi-day camping trips to National Parks such as Zion, Sequoia, and the Grand Canyon.
